When moving or removing applications from a module, be sure to move or remove the relevant pot files for the application in the /trunk/l10n-kde4/templates/messages
and /trunk/l10n-kde4/templates/docmessages folders. Then make sure you add entries to /trunk/l10n-kde4/scripts/process_orphans.txt that note what was done.

There is no need to checkout everything from l10n-kde4, just the templates and scripts folders.
